It is one of the worst disasters in the history of nuclear power generation.]]> 2022-11-20 14:20:56 UTC https://padlet.com/Karentgenedy/koysj0magcf4r5s2/wish/2391444568 Karentgenedy https://padlet.com/Karentgenedy/koysj0magcf4r5s2/wish/2391447015 The Chernobyl disaster occurred when technicians at nuclear reactor, They attempted a poorly designed experiment. They shut down the reactor’s power system and its emergency safety systems, and they removed control rods from its core while allowing the reactor to run at 7 percent power. These mistakes led to an uncontrolled chain reaction that started to have several massive explosions in it.]]> 2022-11-20 14:25:20 UTC https://padlet.com/Karentgenedy/koysj0magcf4r5s2/wish/2391447015 Karentgenedy https://padlet.com/Karentgenedy/koysj0magcf4r5s2/wish/2391454681 The three isotopes were Iodine-131, Strontium-90 and Caesium-137 that released in atmosphere and contaminated several parts of the Europe.]]> 2022-11-20 14:38:24 UTC https://padlet.com/Karentgenedy/koysj0magcf4r5s2/wish/2391454681 Karentgenedy https://padlet.com/Karentgenedy/koysj0magcf4r5s2/wish/2391459863 Iodine-131 collects in the thyroid gland which people exposed to it in chernobyl disaster, it increased the risk of thyroid disease(thyroid cancer.) Thyroid cancer is common that the energy from ionizing radiation breaks the chemical bonds in DNA, resulting in a number of different types of damage. Which resulted that many children and adults died, due to the dangerous Iodine-131 that leads to have a thyroid cancer.]]> 2022-11-20 14:46:59 UTC https://padlet.com/Karentgenedy/koysj0magcf4r5s2/wish/2391459863 Karentgenedy https://padlet.com/Karentgenedy/koysj0magcf4r5s2/wish/2391472610 Once it goes into the body, Strontium-90 is like a calcium and it incorporated into bones and teeth, where it can cause cancers of the bone, bone marrow, and soft tissues around the bone.]]> 2022-11-20 15:08:39 UTC https://padlet.com/Karentgenedy/koysj0magcf4r5s2/wish/2391472610 Karentgenedy https://padlet.com/Karentgenedy/koysj0magcf4r5s2/wish/2391484256 Caesium-137 can cause burns, acute radiation sickness, and even death like in chernobyl disaster. It increases the risk for cancer because of exposure is at high energy of gamma radiation.]]> 2022-11-20 15:24:27 UTC https://padlet.com/Karentgenedy/koysj0magcf4r5s2/wish/2391484256 Karentgenedy https://padlet.com/Karentgenedy/koysj0magcf4r5s2/wish/2391491188 After the accident, radioactive materials were deposited mostly on open surfaces such as lawns, parks, roads, and building roofs, for instance by contaminated rain.  For example, radioactive deposits were larger in areas where it was raining when the contaminated air masses passed. Also, because radioactive strontium particles are heavier than many other radioactive particles, they were deposited within 100 km of the destroyed reactor. ]]> 2022-11-20 15:35:24 UTC https://padlet.com/Karentgenedy/koysj0magcf4r5s2/wish/2391491188 Karentgenedy https://padlet.com/Karentgenedy/koysj0magcf4r5s2/wish/2391493168 2022-11-20 15:37:23 UTC https://padlet.com/Karentgenedy/koysj0magcf4r5s2/wish/2391493168 Karentgenedy https://padlet.com/Karentgenedy/koysj0magcf4r5s2/wish/2391493332 2022-11-20 15:37:41 UTC https://padlet.com/Karentgenedy/koysj0magcf4r5s2/wish/2391493332
